Subject[PATCH v3 2/3] dt-bindings: PCI: qcom: Document msi-map and msi-map-mask properties
Date
The Qcom PCIe controller is capable of using either internal MSI controller
or the external GIC-ITS for signaling MSIs sent by endpoint devices.
Currently, the binding only documents the internal MSI implementation.

Let's document the GIC-ITS imeplementation by making use of msi-map and
msi-map-mask properties. Only one of the implementation should be used
at a time.
